The invention relates to a valve device (2) for a compressed-air system, comprising a pressure-medium inlet (50) that can be connected to a pressure-medium source, at least one pressure-medium outlet (46) that can be connected to a consumer, and at least one vent (48) leading to the atmosphere. The valve device (2) also has a valve piston (12), which is movably arranged in a housing (4) and which moves an aeration piston (24) arranged separate from the valve piston (12) in order to open and close an inlet valve (38). The valve piston (12) is moved by means of an electromechanical linear drive (41), which linearly drives the valve piston (12) in accordance with an electrical control signal fed to the linear drive (41) in order to control pressures present at the pressure-medium outlet (46), e.g., brake pressures in a brake system. The invention further relates to a pressure control module for a compressed-air system of a motor vehicle having at least one valve device (2), and a motor vehicle, e.g., utility vehicle, having at least one valve device (2) and/or at least one pressure control module.
